What is the direction of the electric field caused by the charge at point P?
What is the direction of the electric field caused by the charge at point P? The magnitude of the electric field E produced by a charged particle at a point P is the electric force per unit positive charge it exerts on another charged particle located at that point. The direction of the electric field […]
Do we see in black and white at night?
Do we see in black and white at night? Sensing Light Both rods and cones are sensitive to light. When it gets dark the cones lose their ability to respond to light. The rods continue to respond to available light, but since they cannot see color, so to speak, everything appears to be various shades […]

Is active or passive transport faster?
Is active or passive transport faster? Active transport is a rapid process. Passive transport is a comparatively slow process. What are the 4 methods of passive transport? The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. […]
What describes something in nature without attempting to explain it?
What describes something in nature without attempting to explain it? Unlike a theory, a scientific law describes an observed pattern in nature without attempting to explain it. A hypothesis is a possible explanation for a set of observations or answer to a scientific question. What do we call a description of how something works in […]
What are the two essential conditions for work done by a force acting on an object?
What are the two essential conditions for work done by a force acting on an object? For work to be done, it is essential that some force is applied to the object and the object displaces from its initial position. If these two conditions are satisfied, then the work is done. So, work done= force […]
